Zucchini is one of Georgia's fastest warm-season vegetables, but its speed comes with a catch: squash bugs, vine borers, disease and summer heat can make an early healthy planting look very different later in the season. Timing and succession planting are powerful tools.
UGA's current chart gives a spring window of about April 1–May 15 and a fall window around August 1–August 25. South Georgia can often plant spring crops earlier than middle Georgia, while North Georgia generally runs later. Fall timing reverses that pattern.
UGA commercial guidance notes summer squash can begin producing in roughly 45–55 days and is often planted at intervals to maintain production. That strategy is especially useful in Georgia because insect and disease pressure tends to increase later in the warm season. A younger second planting can sometimes be more productive than trying to keep one exhausted plant alive indefinitely.
Zucchini companion planting should support pollination, airflow and efficient use of space. Flowers and flowering herbs nearby can provide additional resources for bees and beneficial insects. Low-growing crops can fit around the outside of the zucchini's mature canopy if they are not shaded out.
Do not crowd zucchini with pumpkins, cucumbers, melons or other squash-family crops simply because they are “companions.” They can share pests and diseases. Rotate cucurbits to a different area when possible, and leave enough room to inspect stems and leaf undersides.
Squash plants produce separate male and female flowers. The female flower has a tiny immature fruit behind it. Pollen must be moved—primarily by bees—from male to female flowers. Poor pollination can leave that tiny zucchini yellowing and failing to enlarge.
Zucchini can go from ideal to oversized remarkably fast in Georgia warmth. Pick fruits while the skin is tender and before seeds become large. Frequent harvesting encourages continued production and keeps you from discovering a baseball-bat-sized zucchini hidden under a leaf.
Squash bugs, squash vine borers, cucumber beetles, powdery mildew and viral diseases can all become important. UGA notes that disease and insect problems commonly curtail late-season summer squash production. Rotation, sanitation, pollinator protection and early scouting are central to management.

Georgia timing note: statewide dates are planning guides. UGA notes that extreme South Georgia can run roughly two to three weeks earlier in spring than middle Georgia, while North Georgia can run one to three weeks later; fall timing shifts in the opposite direction. Always adjust for local weather and frost dates.
